Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signals transmitted from Mainfl
(England), and Fort Collins (the United States) include both Standard Time and DST
data. When the Auto DST setting is turned on, the watch switches between Standard
Time and DST (Daylight Saving Time) automatically in accordance with the signals.
• Though the time calibration signals transmitted by the Fukushima and Fukuoka/
Saga, Japan transmitters include summer time data, summer time currently is not
implemented in Japan (as of 2013).
• The default DST setting is Auto DST (

(summer time) manually.

Radio-controlled Atomic Timekeeping Precautions
• Strong electrostatic charge can cause the time setting to be thrown off.
• The time calibration signal bounces off the ionosphere. Because of this, such
factors as changes in the refl
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
• Even if the time calibration signal is received properly, certain conditions can cause
the time setting to be off by up to one second.
• The current time setting in accordance with the time calibration signal takes priority
over any time settings you make manually.
• The watch is designed to update the date and day of the week automatically for the
period January 1, 2000 to December 31, 2099. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2100.
• This watch can receive signals that differentiate between leap years and non-leap
years.
• Though this watch is designed to receive both time data (hour, minutes, seconds)
and date data (year, month, day), certain signal conditions can limit reception to
time data only.
